Abstract :
Using an experimental apparatus modeled for a gas-insulated switchgear (GIS), the influence of the arc duration on the breakdown voltage between the contact and the grounded tank of the GIS was investigated in the case that the arc was kept ignited in the contact area. From the result, characteristics of the breakdown voltage vs. the arc duration were found to be divided into six stages and the characteristics in each stage were estimated
